Effects of introducing dynamic constraints for buckling to truss sizing optimization problems

Autor: Petrović Nenad, Marjanović Nenad, Kostić Nenad, Blagojević Mirko, Matejić Miloš, Troha Sanjin

Publikováno v: FME Transactions, Vol 46, Iss 1, Pp 117-123 (2018)

In this paper the effects of adding buckling constraints to truss sizing optimization for minimizing mass are investigated. Introduction of buckling testing increases the complexity of the optimization process as Euler buckling criteria changes with

Steric effects on the rate of hydrolysis by palladium(II) complexes of the C-terminal amide bond in a series of methionine-containing dipeptides AcMet-Aa

Autor: Johnson Wade T., Kostić Nenad M.

Publikováno v: Journal of the Serbian Chemical Society, Vol 69, Iss 11, Pp 887-899 (2004)

A series of N-acetylated, methionine-containing dipeptides designated AcMet-Aa containing various C-terminal amino acids designated Aa are hydrolyzed in aqueous solution at 50 ºC and 0.95 < pD < 1.10 in the presence of three cis-[Pd(L)(H2O)2]2+ comp
